Use the formula for the volume of sphere

V = %284%2F3%29%2Api%2Ar%5E3 = %284%2F3%29%2Api%2A%2813%2F2%29%5E3 = %284%2F3%29%2A3.14%2A6.5%5E3 = . . .

Please calculate it yourself.

Diameter: 13 therefore radius: 13/2= 6.5
V = 4/3πr^3
V = 4/3π(6.5)^3 Use your calculator to find your answer. Email if you still don't understand.
